- Be'it known that '1, CHARLES E. SORIBNER, a citizenof the UnitedStates, residing at Jericho, in the county of Ohittcnden and State ofVermont, have invented a certain new and useful lmpro'vement inElectrical Selecting Appliances, of which the following is a fulhclear,concise, and exact description.

My invention relates to electrical selecting appliances; and its objectis to provide an improved device for controlling the selective Operationof apparatus in an electric circuit.

M'y-invention consists in general ofa device for producing any'desirednumber of quick breaks or interruptions in an electric circuit tooperate apparatus therein with mechanism adapted to be set to determine.the number of breaks to becreated or, in

Other words, which will render the device inoperative for, breaking thecircuit after its actuationthe predetermined number of times.

1 have found the device of my invention of special. adaptability for usein connection with automatic tclephone-exchanges to be located at thesubstation of a line and employed to operate asolector at the centraloIIice adapted to connect the line with'another in the exchange, suchselector. requiring for its operation quick breaks in the circuit.

' My invention contemplates a quick-break contact device comprising amovable contact member having a normal resting contact anvil, withmechanism, such as a leverand a pawl carried -thereby,; for moving saidmember away from its anvil and simultaneously closing a shunt around themember. and its anvilthat is, around the, separated contacts. Means areprovided for withdrawing said mechanism from the cdhtact member at theproper time to release the member and open the said shunt. .The memberis arranged to be automatically returned when releasedto its normalposition against its anvil.

With this.construction the break in the electrical connection betweenthe member and its contact exists only duringthe interval in whlchthccontactnieniber returning to its 'norin'al position, thereby making avery quick and short break. I Another. feature of the invention consistsm the provlsion of mechgmisnj adapted to,

. rend or the cojntactdevice inoperative to createa break injthe circuitafterits operation apredetermined number of times dependent upon theposition to which said mechanism is set or adjusted; To this end 1preferably provide a selectOr Wheel with a pointer there for, said wheeland pointer being adapted to be moved to set the pointer at any positionon a scale or dial, which maybe numbered or marked in any suitable Way.A device such as the lever above mentioned is provided for stepping saidwheel back toits normal position, the quick-break contact device beingwheel. The contact device is rendered inoperative to create a'break uponthe return of the wheel to its normal about said. contact device.

I will describe my invention more particw .larly by refefrenpe to theaccompanying drawings, wherei'n Figure 1 a front elevation of asignal-box mechanism is mounted uponga frame-plate a,

of conducting material, secured to the inner face of the cover of thesignalalbox A A-movable contact member, such' as the pivotedcoiitact-armb, is mounted upon said plate but insulated therefrom,having a normally resting contact-anvil b ioun'teddirectly upon theplate. Means are provided for moving said: arm away from its anvil,consistingl, preferably, of a manuallyoperated osition, preferably j (bymeans a shunt'c osed by the wheel I operated by the. lever in each stepof the The same letters ofreif'ere nce are used -le've'rc, pivoted tosaid plate a and carryinga pawl 0, adapted in the initial movement ofthe lever toinove said contact-arm b, said pawl preferably engaging apin b carried on the arm I).

After the lever has been moved to bring the pawl intoengagement with said contact member, as shown in Fig. 3, and as thelever continues its movement the pawl is suddenly Withdrawn fromengagement with the contact-arm, releasing said arm and opening theshunt about the separated contacts. This may be accomplished by estop-finger d, mounted upon the frame and adapted during the movement ofthe lever and its pool to er. lie spur o and throw the pewl out .nt"with said pin 5.
